A Bollywood crew has arrived in Vietnam’s Quang Tri province to begin filming Silaa, the first Indian movie to highlight the stunning caverns of Phong Nha-Ke Bang National Park, including the world’s largest known cave.
Dang Dong Ha, deputy director of the Quang Tri Provincial Department of Culture, Sports and Tourism, welcomed the crew.
He noted that the film is a terrific opportunity to promote Quang Tri’s tourism potential not just to Indian travellers but also to global audiences, Viet Nam News reported.
The official added that this collaboration could pave the way for film-related tourism services in the province.
Local authorities, meanwhile, reiterated their support for filmmakers and pledged to provide the best conditions for future productions in Quang Tri.
Strict access rules limit crew inside cave
Silaa, directed by Omung Kumar, will be the first Bollywood production to film inside Son Doong Cave, the largest known cave in the world.
Nguyen Chau A, chief executive officer of Oxalis Adventure, the official operator of Son Doong Cave tours, has confirmed a signed agreement with the Indian film team.
Due to strict environmental protection rules, only 12 crew members will be permitted to shoot inside the cave, he said.
Additional scenes will be filmed at Hang Tien, Tu Lan, and Chuot Caves in the Tan Hoa region.
Filming in Quang Tri will run until August 12.
The global release of Silaa is expected in 2026, with the lead roles played by well-known figures in Bollywood cinema, actors Harshvardhan Rane and Sadia Khateeb.

Son Doong’s international fame continues to grow
Son Doong Cave spans nine kilometres, measures 150 metres wide, and features ceilings over 200m high, solidifying its status as the world’s largest known cave and a national treasure of Vietnam.
It was previously showcased live by ABC News in 2015 on Good Morning America.
The cave now lies within the new Quang Tri province, formed by merging the former Quang Binh and Quang Tri provinces.
This change is part of Vietnam’s broader administrative restructuring, which reduced the number of provinces and cities nationwide from 63 to 34.
